Cont'd from https://github.com/kinu-garage/hut_10sqft/issues/1010#issuecomment-2199204246 toward a bigger goal https://github.com/kinu-garage/essay_in_idleness/issues/150

glut is missing on my platform. 

$ make

I might want to keep the host environment so may do this on Docker.

Building instruction/FAQ

If you are using a synaptic-based distribution, like Ubuntu, run:

sudo apt-get install freeglut3-dev glew-utils libglew1.6-dev libfreeimage-dev

Don't want to corrupt the host too much so going for Docker. https://qiita.com/asuka1975/items/5384ff4c20accb87cdca is helpful.

On host

export PATH_LOCAL_WS=/home/noodler/link/ROS/130s/prooving_grounds/mooc/edx.org_CSE167x-UCSD_ComputerGraphics
export SRC_DOCKERIMG=nvidia/opengl:1.0-glvnd-devel-ubuntu22.04
export RESULT_DOCKERIMG=d130s/mooc:edx.org_CSE167x-UCSD_ComputerGraphics
docker run --network host  \
  -v $PATH_LOCAL_WS:/cws/src  \
  -v /dev:/dev  \
  -it $DOCKERIMG bash

docker run -it --rm \
        --gpus all \
        --hostname=gltest \
    --volume $PATH_LOCAL_WS:/cws/src  \
        -e DISPLAY=$DISPLAY \
        -e NVIDIA_DRIVER_CAPABILITIES=all \
        -v /tmp/.X11-unix:/tmp/.X11-unix \
    $SRC_DOCKERIMG

Then in container,

# apt update && apt-get install -y build-essential \
 freeglut3-dev \
 glew-utils \
 libglew1.6-dev \
 libfreeimage-dev

This won't become my Colcon/ROS2 project and also it'll be better to eliminate external dependencies so just following basic path without relying on Colcon, rosdep etc.

libglew1.6-dev doesn't seem to be found. But a newer version is already installed. Maybe nvidia's Docker image already installs it?

# apt-get install -y libglew2.2

If your source files compile, but you have link errors, such as /usr/bin/ld: final link failed: Nonrepresentable section on output, it is likely our libraries, provided for convenience, are outdated, and don't work with your modern Linux distribution. Try removing the -L./lib/nix in the Makefile (and possibly the -I./include although this is not required). This will ensure the code simply uses the system libraries. If successful, you will need to make this change for all homeworks in the course.

So omitted the included lib files.

#INCFLAGS = -I./glm-0.9.7.1 -I./include/ -I/usr/X11R6/include -I/sw/include \
INCFLAGS = -I./glm-0.9.7.1 -I/usr/X11R6/include -I/sw/include \
        -I/usr/sww/include -I/usr/sww/pkg/Mesa/include
#LDFLAGS = -L./lib/nix -L/usr/X11R6/lib -L/sw/lib -L/usr/sww/lib \
LDFLAGS = -L/usr/X11R6/lib -L/sw/lib -L/usr/sww/lib \
        -L/usr/sww/bin -L/usr/sww/pkg/Mesa/lib -lGLEW -lglut -lGLU -lGL -lX11 -lfreeimage

A lot of lines mention grew so I suspect it missing. However I'm told before even running very first make:

# apt-get install -y libglew2.2
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
libglew2.2 is already the newest version (2.2.0-4).
0 upgraded, 0 newly installed, 0 to remove and 71 not upgraded.

libglew-dev is available on Ubuntu 22.04, which shows the same version 2.2.0-4 as the one above so this may not matter.

So I'm not yet sure where the error is arising from. I guess it's the linker who's shedding errors as I see errors only occurring with /usr/bin/ld AFAICT.

To continue narrowing down, I removed the libs I installed and reverted makefile content.

apt purge libfreeimage-dev libglew2.2-dev && apt autoremove

I confirmed that by removing the commented line then the output became different, which is the one at the bottom of https://github.com/kinu-garage/hut_10sqft/issues/1052#issuecomment-2199319735 that complains something about the included libs incompatibility.

/usr/bin/ld: ./lib/nix/libGLEW.a(glew.o): relocation R_X86_64_32S against `.rodata' can not be used when making a PIE object; recompile with -fPIE
/usr/bin/ld: failed to set dynamic section sizes: bad value

Now different, more classic error.

I guess make ended w/o errors. I think libglew2.2 is not supposed to be installed manually (install libglew-dev instead)?
